This chunky cowl is super simple to make, with a double seed stitch pattern, and seamless from being worked in the round.
CO 90, join without turning.
Rows 1 and 2: *k1, p1; rep from * to end around
Rows 3 and 4: *p1, k1; rep from * to end around
Rep rows 1-4 until you have the desired width.
BO loosely and weave in all ends.
My finished cowl is 14"x40".
